Claim
1. A method for random access in a wireless communication system including a base station and a wireless terminal, the method comprising:
at the wireless terminal,
selecting a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and
transmitting, during or after completion of the random access using the selected random access preamble from the selecting, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access.', 'at the wireless terminal,', 'selecting a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and', 'transmitting, during or after completion of the random access using the selected random access preamble from the selecting, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access.
2. The method for random access according to claim 1, wherein the third information indicates that a buffer of the wireless terminal has uplink data.
3. The method for random access according to claim 1, wherein the wireless terminal receives the first random access preamble used for the first random access from the base station.
4. The method for random access according to claim 1, wherein the wireless terminal receives the second random access preamble used for the second random access from the base station.
5. A wireless communication system comprising:
a base station; and
a wireless terminal communicating with the base station, wherein
the wireless terminal selects a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and
transmits, during or after completion of the random access using the selected random access preamble as selected by the wireless terminal, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access; and the base station performs a data communication with the wireless terminal.', 'a base station; and', 'a wireless terminal communicating with the base station, wherein', 'the wireless terminal selects a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and', 'transmits, during or after completion of the random access using the selected random access preamble as selected by the wireless terminal, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access; and the base station performs a data communication with the wireless terminal.
6. A wireless terminal comprising:
a selector that selects a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and
a transmitter that transmits, during or after completion of the random access using the selected random access preamble as selected, among the first random access and the second random access, information with a response message to be transmitted to a base station during third random access.', 'a selector that selects a random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access; and', 'a transmitter that transmits, during or after completion of the random access using the selected random access preamble as selected, among the first random access and the second random access, information with a response message to be transmitted to a base station during third random access.
7. A base station comprising:
a signature managing unit that manages a random access preamble used for random access and allocates the random access preamble for a wireless terminal; and
a transmitting-and-receiving unit that receives information selected by the wireless terminal which selects the random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access and transmits, during or after completion of the random access using the selected random access preamble as selected, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access.', 'a signature managing unit that manages a random access preamble used for random access and allocates the random access preamble for a wireless terminal; and', 'a transmitting-and-receiving unit that receives information selected by the wireless terminal which selects the random access preamble among a first random access preamble used for first random access and a second random access preamble used for second random access in case of receiving a request requesting for new random access among the first random access and the second random access while another random access among the first random access and the second random access is already ongoing, to continue with the ongoing random access or start with the new random access and transmits, during or after completion of the random access using the selected random access preamble as selected, among the first random access and the second random access, information with a response message to be transmitted to the base station during third random access.']
